FIBEPROOF BUILDING CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed February 24, 1908. Serial No..417,410.

- To all whom it may concern:

Be it known that I, GUSTAV EDWARD Esonnn, a CJtlZBIl of the l'nited States, and a resident of the borough of Manhattan,

-'. city, county, and State of'New York, have invented a certain new and usefullmprovewent in Fireproof Building Construction, of which the following is a specification, ac companied by drawings.

This invention relates to fire proof building construction, more particularly to ceiling construction, although the -invention may be used in any connection in which it-is found applicable.

The objects of the invention are to produce a rigid and cheap construction, which is easy to assemble and leaves practically nothing to the efficiency of workmen, because the mode of construction is a mechanical process throughout.

Further objects of the invention will hereinafter appear and to these ends the invention consists of a construction for carrying out all of-the above objects embodying the features of construction, combination of elements, and arrangement of parts, substantially hereinafter fully described and claimed in this specification, and shown in the accompanying drawings, in which Figure l is a perspective view partly in section, illustrating one form of my improved fire proof construction; Fig. 2 is a transverse sectional view of one form of the construction corresponding to Fig. l, with the mold-boards in place; Figs. 3, 4 and 5, are perspective views of portions of suitable forms of furring bar for use in the construction; Figs. 6, 'Z and 8 are perspective views of portions of modified forms of the .t'urring bar; Fig. 9, is a perspective view of a portion of a furring bar provided with improved means for securing the bar to a beam or other support; Fig. 10, is a perspective view of a portion of a furring bar like Fig. 9, provided with a diiferent form of hooked-shaped tongue or stirrup; Fig. 11, is a transverse sectional View of a beam having a furring bar like that shown in Fig. 10, secured thereto; Figs. 12 and 13, are transverse sectional views of a beam illustrating modified forms of clips for securing the furring bar to the beam.

Referring to the drawings, and more particularly to Figs. 3, 4; and 5, a furring bar A is shown comprising in this instance an angle bar having the flanges B and C. At

' bars.

suitable intervals in the length of the horizontal flange B, l'looked-shaped tongues 01'' stirrups D are cut longitudinally out of the flange and bent out of the plane of the flange to form hangers. In order that the hookedshaped stirrups D may be in proper position to supportcross furring bars transversely of the furring bar A, the hook is twisted at E Fig. 3 into a plane at an angle to the flange.

B. By cutting the" hooks D longitudinally out of the metal of the flange B the whole bar is not substantially weakened because the upright leg is not reduced, and because longitudinally extending webs areleft at each side of the slots. The twistE in the shank of the'hook D also strengthens the hot k and makes it more rigid.

In Fig. 4:,the angle bar. A, has one or more hooks D cut transversely out of the flange B and bent out of the plane of the flange. In this instance, the hook D, is in proper relationshi to support cross furring bars Without twisting the shank of the hook. This construction, however, weakens the angle bar A to a much greater extent than in the construction shown in Fig. 3.

In-the modification shown in Fig. 5, one or more straight tongues are cut longitudinally out of the flange B and bent into hooked-shaped form as illustrated at-F to support cross furring.

Figs. 6, 7 and 8 illustrate furring bars comprising flat strips G instead of angle In Fig. 6, one or more hooks H are cut longitudinally out of the length of the bar G and bent out of the plane of the bar with a slight twist at the point I to bring the hooks into position to support cross furring.

In Fig. 7 one or more hooks H are cut transversely out of the body of the bar G which weakens the bar to some extent, and in Fig. 8, straight tongues are cut longitudinally out of the bar G and bent into hookedshaped form as shown at J, with a twist at I to bring the hooks into position to support cross furring.

Fig. 1 illustrates a for a ceiling, utilizing the furring bar A like that shown in Fig. 3 with the hookedshaped tongues or stirrups D cut longitudi nally out of the horizontal flange B and bent and twisted into the desired plane for supporting the cross furring bars K.

It is to be understood that a furring bar A is connected to each beam L and these furfife proof construction ring bars may be angle bars or straight bars as desired. The cross furring K may be in the form of channel bars as shown, or any other suitable form. The furring bars A are arranged longitudinally of the beams L and suitable means are provided for securing the uprightflanges C of the bars A, to

the lower flanges of the I-beams L. In this instance, I have shown an improved form of clip for this purpose, comprising the bent members a and b which grip the lower flanges of the I-beams and are suitably se-- cured to the furring bar as by means of the bolt 0. The metallic lath P is suitably secured to the cross furring bars K as by means of the wires Q or any other means may be used.

There are a great many advantages of the fire proof construction disclosed in Fig. 1. By reference to Fig. 2, it will be seen that the horizontal flange B of the furring bar A forms in effect a'portion of a horizontal mold board for the concrete beam. In forming the beam the studs R are placed temporarily underneatl'i the I-beams'L, the mold boards S are placed at each side of the beam and the horizontal mold board T extends up to the angle bar A thereby forming an inclosed form into which to pour the concrete U. After the concrete has set, the studs R and mold boards are remo ed. Preferably, the top of the vertical flange C of the furring bar A is arranged at a sufficient distance below the bottom of the I beain L to permit the concrete to entirely surround the vertical flange of the furring bar and inclose the same, thus fire-proofing the beam.

According to this construction, the clips a, 7) for the furring bars may be arranged at substantial distances apart in the length of the beams, a few in number, and there may be as many hooksor stirrups D as desiredat very much closer intervals apart. The whole construction is rigid and cheap and easy to assemble, because the hooks 1) form an integral part of the furrii'lg bars. Since the hooks I) are all the same length, practically nothing is left to the etliciency of the workmen in constructing the ceiling and the ceiling is necessarily level throughout. The hooks I) and the other forms of hooks illustrated and described, should be left suiticiently open to permit the cross furring bars K to be readily dropped thereinto. The toe D on the hook I) prevents the cross furring bar K from falling out. This toe is indicated on each of the other forms of the hooks by the same reference numeral D In Fig. 9, a modified form of furring bar A is shown comprising an angle bar having clips 9 and It cut out of the upright flange and bent at an angle to said flange to enable the furring bar to be secured to one of'tthe beams L or other support. These cl ps 9 and h are arranged at suitable intervals in the length of the bar and they are twisted at y to bring them into the proper plane to enable them to be secured to the beam. By cutting the clips or tongues g and II. longitudinally out of the bar A, said bar is not weakened to an appreciable extent.

In Fig. 10, a furring bar V is shown, having the securing clips 9 and 7t and a separate and independent hook 71! inserted through an aperture infthe horizontal flange of the bar. In Fig. 11, the furring bar V is shown secured to the I-beam L by means of the clips 9 and h, and the hook p is provided with a bent head 9 instead of a bolt head 1 like the hook is in F 10.

In Fig. 12, the furring bar A is secured to the beam L by means of the clip 8 which passes through an aperture t in the upright flange of the fur-ring bar A.

In Fig. 13, instead of having a. separate aperture through which to pass the clip .9 said clip is passed through the slot formed by the bent hook D, and thus supports the furring bar A. These clips 8 a: d s as shown are provided with the loops '2), and o and the bent ends 10.

According to my invention, it is to be understood that the different forms of furring bars and clips for securing the bars to the beams, may be interchangeably used, and may be assembled in varying combination of parts, for I do not.- limit myself to any particular figure or combinations of figures.

The invention may also be used in con.- nection with torra-cotta. arches, or arches of any other material.
